How to fix iPhone 16 Pro Max Freezing issues?

I just got my new phone today and I'm trying to transfer everything over from my old phone via the iCloud setup. I got through all of the initial setup screens but now that I'm on the home screen, the phone keeps freezing if I try to open any application. It either doesn't open the app at all, or the app opens and then becomes non-responsive, and then after a few minutes the screen goes black and shows a small loading icon and eventually goes back to the lock screen.


In addition, power + volume button reset method doesn't work, so there's no way to force a restart to see if that fixes the problem

So the folks talking about doing a restore again phone-to-phone were spot on.


My iPhone 16 Pro Max would lock up, freeze, etc after I restored from iCloud. For a long time I couldn’t even get to the SETTINGS on the phone to try to erase. I learned over time that if I just left the phone alone for long enough (overnight, or maybe 4+ hours) and didn’t reboot it, I was eventually able to get to the SETTINGS without it freezing.


Once I was able to get into the settings, I did an “erase all content and settings”, but saved the eSIM. Once done, I started anew and restored phone-to-phone. Everything worked perfectly for there on. The eSIM was there, and no freezing issues at all now. WHEW.. Thanks much to the folks who mentioned this.

I am having this exact problem after “upgrading” from 13 Pro Max to 16 Pro Max.


My phone constantly freezes, slows down, goes unresponsive, restarts itself eventually. I’m frequently unable to even open Settings on my phone.


ATT store and Best Buy (geek squad) were both unable to fix it after multiple restores and resets. They recommended calling Apple, but I find it hard to believe they’ll have any other solution aside from resetting it again.


How am I supposed to fix this issue if I no longer have my 13 to restore from? I only have iCloud backups.

Same here. Unfortunately Apple Tech Support don’t read this topic to advice the solution when you call them.

I have traded my old iPhone so can’t restore iPhone to iPhone but I’m trying to back up the faulty iOS to iMac and restore to iPhone. My concern is that the new backup will have faults.

Could I restore from iPad?

Is the issue due to Wifi privacy settings and would iCloud restore over cellular work?

I am having same issue also. When I turn on the phone the hello msg came and I put my 15pro max near to transfer the data to new one. But after some transfer it’s freeze and only come hello msg with some effect. I can not go ahead or turn off the phone. It’s too hot . Then I let to drain battery to zero. Now it’s turn off. When I charged again to check it’s same. I talked to the apple service center also they said in nepal it’s not lunched yet so they can not do anything. I bought it in dubai.

I have had nothing but issues with the iphone 16 pro max. from starting it up on sept 20 it kept freezing so i kept having to restart it and it took me 3 hours to activate. and ever since then my camera doesn’t work, it keeps crashing. my keyboard is either putting in the wrong buttons, super slow or not working at all. the screen keeps freezing. and even sometimes when i try to like a post or something it doesn’t let me press it until like the 5-6 try. it overheats and it’s super slow and laggy. i’m super disappointed

As an update, still having intermittent issues with the phone locking up when opening apps (doesn’t seem to be much consistency on which app causes the issue: sometimes settings, sometimes messages, sometimes Hue, etc etc etc. the only “fix” I’ve found is to not use the phone for awhile (usually let it sit for 20-30 minutes) and then that app will work again (until the issue recurs with another app or apps).


Sometimes the phone reboots during this time (get the prompt to enter passcode before Face ID will work) but other times not.


I know some people report that they fully resolved the issue but restoring phone to phone (vs iCloud backup) but my old phone is long gone at this point (trade-in) so not sure how to fix.

got a new Verizon - apple 16 pro max -


booted up fine and transfer started - software update downloaded and started to install - the phone went to sleep. When swiping up - I saw a flash of the code screen and went back to the hello screen.


i tired to shut it down but only saw a flash of swipe off screen - but will not active


I have done a volume up, volume down and hold power - it reboots and goes back to the same scenario.


the phone is very warm.


apple support had me to plug phone to my Mac- iTunes and the Mac does not recognize the phone either- it’s does show charging - nothing else


apple support said the heat was due to being hung up in the update.


i have appt Monday…. Just wondered if anyone had any miracles cures ….


this has been so frustrating to say the least


needless to say- these were upgrades and the rest of the phones went good


this is my wife’s and the last to activate…. Arghhh!

How are any of the problems described in this thread okay? . . ..

It's not okay to have these issues with a new iPhone release. C'mon Apple!!


I wonder if Apple's AI could offer guidance with these problems?

Oh wait, it's not yet available for the iPhone that's built for Apple AI. !!!!


And this complaint is coming from an Apple fan. I have more Apple products than I know what to do with. Although as Apple's products continue to pale, I'm getting some ideas.

i got my 16pro max today. Did the start up process, kept freezing. Did update,

restarted and then froze on hello screen and when I swipe up to get to passcode. It goes right back to the hello screen, no chance to type in code. I’ve restarted it, left it off for a while…. Etc. has anyone found anything that will help? I have no phone at the moment. And no way to call anyone or answer calls.
